The Smith and Bybee Wetlands Natural Area is virtually invisible in this industrial area and yet it is one of the largest urban wetlands in the United States. You can access this natural area by car or bus. However, if you're feeling very ambitious, add this destination as you walk or bike the 40-mile Loop Trail that runs along the edge of the park. There are bike racks where you can lock up your bike since bicycles and dogs are prohibited on the Interlakes Trail to prevent wildlife from being disturbed.

The Interlakes trailhead is located at the beginning of the entrance road. The main parking lot is about a half-mile from here. There are accessible parking spaces, a drinking fountain and accessible bathrooms at this parking lot. A covered picnic area is located here, also, but metal columns block wheelchair access to the picnic benches. Although, access could be made by entering through the grass, the picnic benches do not have extended ends to allow wheelchair use.

Spring is the best time to go bird-watching or to see the Western painted turtles sunning on the logs. Along the Interlakes Trail, there are three designated wildlife viewpoints, two are covered – all are off-trail at wide unmarked junctions. Although the trail is paved, roots may cause bumps and ruts in the asphalt surface. The surface of the wildlife viewpoints is metal grating without edge protection. This could be hazardous for some wheelchair users. Some of the transitions from trail to the grating are steep and may have a lip.

This urban wetland can be explored by trail or by boat. There is a canoe launch at the far end of the entrance road, about a half-mile from the main parking lot. You can park along the road. The trail down to the water is steep in spots. The trail ends before reaching the water. This area is usually muddy.
